When ye pray, say, Our Father… – Luke 11:2

“Lord, if I call Thee King Thou wilt say, ‘Thou art a rebellious subject; get thee gone.’ If I call Thee Judge Thou wilt say, ‘Be still, or out of thine own mouth will I condemn thee.’ If I call Thee Creator Thou wilt say unto me ‘It repenteth Me that I made man upon the earth.’ If I call Thee my Preserver Thou wilt say unto me, ‘I have preserved thee, but thou hast rebelled against Me.’ But if I call Thee Father, all my sinfulness doth not invalidate my claim. If Thou be my Father, then Thou lovest me; if I be Thy child, then Thou wilt regard me, and poor though my language be, Thou wilt not despise it.” …When I talk to my Father, I am not afraid He will misunderstand me; if I put my words a little out of place He understands my meaning somehow. When we are little children, we only prattle; still our father understands us…  So, when we come to God, our prayers are little broken things; we cannot put them together, but our Father will hear us. Oh! what a beginning is “Our Father,” to a prayer full of faults, and a foolish prayer perhaps, a prayer in which we are going to ask what we ought not to ask for! “Father, forgive the language! forgive the matter!” as one dear brother said the other day at the prayer meeting. He could not get on in prayer, and he finished up on a sudden by saying, “Lord, I cannot pray to-night as I should wish; I cannot put the words together; Lord, take the meaning take the meaning,” and sat down. That is just what David said once, “Lo, all my desire is before Thee”-not “my words” but “my desire” and God could read it. We should say, “Our Father,” because that is a reason why God should hear what we have to say. ~ C.H. Spurgeon
